My research focuses on how different environmental factors influence carbon cycling in terrestrial ecosystems and how changes in these ecosystems feed back to the climate system. I am particularly interested in the role of nutrient availability and mycorrhizal fungi in ecosystem carbon cycle - climate feedbacks. For this research, I use different approaches: manipulation experiments testing specific hypotheses, syntheses of manipulation experiments to determine overarching patterns in responses to anticipated global changes, syntheses of observational field data to unravel responses to ongoing global changes, and satellite imagery to study vegetation dynamics from space. Especialy the synthesis studies have been a great inspiration to find data and metrics to usefully compare different sites and experiments.
